Product details

Overview

PUMH13/ZLX from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363-3 (SC-88) package, rated for 50 V V_CEO, 100 mA output current per transistor, with integrated bias resistors R1 = 4.7 kΩ and R2 = 47 kΩ (R2/R1 = 10). It functions as a compact, pre-biased logic-level switch pair for digital signal routing and low-current peripheral driving in space-constrained PCBs.

For engineers reviewing the PUMH13/ZLX datasheet, PUMH13/ZLX pinout, PUMH13/ZLX application, or PUMH13/ZLX equivalent, this page delivers verified pin assignments, real-world use cases in I/O buffering and level translation, confirmed thermal derating curves, and validated alternatives with explicit resistor-ratio and polarity differences.

Technical Context

The PUMH13/ZLX integrates two matched NPN transistors with monolithically embedded base bias networks-each featuring a 4.7 kΩ input resistor (R1) and a 47 kΩ feedback resistor (R2)-enabling direct TTL/CMOS-compatible switching without external bias components. Its dual-emitter-grounded topology supports independent control of two loads with shared ground reference.

Designed for operation up to 150 °C junction temperature, it delivers guaranteed h_FE ≥ 100 at I_C = 10 mA and V_CE = 5 V, with V_CE(sat) ≤ 100 mV at I_C = 5 mA / I_B = 0.25 mA, ensuring low-loss switching in battery-powered and thermally constrained systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial logic interfaces.
I_O	100 mA per transistor - Continuous output current rating; sufficient for LED segment drivers and small-signal relay coils.
R1	4.7 kΩ ±28% - Input bias resistor value; sets base current for predictable turn-on with 3.3 V or 5 V logic.
R2/R1	10 ±20% - Feedback-to-input resistor ratio; stabilizes operating point against h_FE variation across temperature.
P_tot (per device)	300 mW at T_amb ≤ 25 °C - Total power dissipation limit on FR4 PCB; defines maximum simultaneous switching duty.
f_T	230 MHz typical - Transition frequency; supports reliable switching up to ~10–20 MHz digital signals.
V_I(on)	0.9–1.3 V - On-state input voltage threshold; ensures clean logic-high recognition with standard CMOS outputs.

Pinout & Package

SOT363-3 (TSSOP6) plastic surface-mount package: 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering on FR4 PCBs with standard stencil-defined solder paste volumes.

Pin/Terminal	Circuit Role	Design Meaning
1	GND1	Emiter connection for TR1; provides local ground return path for first transistor's load current.
2	I1	Base input for TR1; accepts logic-level drive through internal R1; no external pull-down required.
3	O2	Collector output for TR2; active-low sink output when TR2 is switched on.
4	GND2	Emiter connection for TR2; independent ground node allowing separate load referencing.
5	I2	Base input for TR2; electrically isolated from I1; enables independent control of second channel.
6	O1	Collector output for TR1; complements O2 for dual-channel low-side switching.

Key Features

Feature	Design Value
Dual NPN RET architecture	Two fully independent, pre-biased NPN transistors in one 6-pin package-reduces board area by >40% vs discrete equivalents.
Integrated R1/R2 network	4.7 kΩ input + 47 kΩ feedback resistors per channel-eliminates four external resistors and associated placement cost.
Guaranteed V_CE(sat)	≤100 mV at I_C = 5 mA - Minimizes conduction loss in always-on or PWM-driven loads like status indicators.
Wide ambient range	−65 °C to +150 °C operating temperature - Supports deployment in automotive under-hood and industrial motor-control environments.
Low input threshold	V_I(on) ≤ 1.3 V - Ensures reliable activation from 1.8 V and 3.3 V microcontroller GPIOs without level-shifting.

Applications

LED Segment Driver

Microcontroller I/O Expander

Use Scenario: Driving individual segments of a 7-segment display from a microcontroller with limited GPIO count and no external driver IC.

IC Role / Device Role / Timing Role: Dual low-side switch providing current-sinking paths for common-anode displays; each channel controls one segment independently.

Use Value: Eliminates need for eight discrete transistors and sixteen bias resistors-reducing BOM count by 75% and layout area by 60%.

Use Scenario: Extending GPIO capability of an ARM Cortex-M0+ MCU to interface with multiple pushbutton inputs and status LEDs.

IC Role / Device Role / Timing Role: Logic-level translator and buffer-accepts 3.3 V button pulls-up and drives 5 V LED anodes via open-collector configuration.

Use Value: Enables direct connection between mixed-voltage domains without level shifters; VI(on)/VI(off) specs ensure noise-immune detection at 10 kHz debounced rates.

Industrial Sensor Interface

USB Peripheral Power Control

Use Scenario: Isolating and conditioning digital alarm outputs from analog sensor modules (e.g., temperature, pressure) before feeding into PLC input cards.

IC Role / Device Role / Timing Role: Signal conditioner and current amplifier-converts weak sensor logic pulses into robust 100 mA sink outputs compatible with 24 V DC PLC inputs.

Use Value: Withstands 50 V transients and operates reliably at 85 °C ambient-meeting IEC 61000-4-5 surge immunity requirements for factory-floor deployments.

Use Scenario: Enabling/disabling VBUS power to USB peripherals (e.g., HID devices, serial adapters) based on host enumeration status in embedded USB hubs.

IC Role / Device Role / Timing Role: Controlled load switch-TR1 enables VBUS path while TR2 monitors enumeration flag; both share thermal budget within single package.

Use Value: Achieves <10 µA quiescent current in off-state (ICEO ≤ 5 µA at 150 °C), meeting USB Battery Charging v1.2 standby leakage limits.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual NPN pre-biased transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
PUMD13	NPN/PNP complement; R1 = 4.7 kΩ, R2 = 47 kΩ but second transistor is PNP	Required for complementary push-pull output stages or level inversion where sourcing + sinking is needed	Select when bidirectional signal control or rail-to-rail swing is required instead of dual-sink operation
PUMB13	PNP/PNP configuration; same R1/R2 values but both transistors are PNP	Used in high-side switching applications where load connects to V_CC and device switches return path	Choose for active-high control topologies-e.g., enabling 5 V rails or controlling PMOS gate drivers

Compared with PUMH13/ZLX, PUMD13 offers complementary output polarity essential for push-pull buffers, while PUMB13 supports high-side switching; neither matches the dual-NPN sink capability of PUMH13/ZLX for common-anode or ground-referenced loads.

FAQ

What is the maximum continuous current per channel?

The PUMH13/ZLX supports 100 mA continuous collector current per transistor under T_amb ≤ 25 °C with proper PCB copper area. Derating applies above 25 °C ambient: total device power must stay ≤ 300 mW, and junction temperature must not exceed 150 °C. At 70 °C ambient, maximum usable current drops to ~65 mA per channel based on the published 417 K/W R_th(j-a).

Can PUMH13/ZLX replace discrete transistor + resistor combinations?

Yes-each channel replaces one NPN transistor plus two bias resistors (base input and base-emitter feedback). The integrated R1 = 4.7 kΩ and R2 = 47 kΩ match common design values for 3.3 V/5 V logic drive, eliminating layout errors, solder joint failures, and inventory overhead associated with four discrete passives per channel.

Is thermal performance affected by PCB layout?

Yes-thermal resistance depends critically on PCB construction. The datasheet specifies R_th(j-a) = 417 K/W for a single-sided FR4 board with 35 µm tin-plated copper and standard footprint. Adding internal ground planes or thermal vias can improve heat dissipation by up to 35%, but unmodified layouts must respect the 300 mW total device power limit at 25 °C ambient.

How does the R2/R1 ratio impact switching behavior?

The R2/R1 = 10 ratio establishes negative feedback that stabilizes the transistor's DC operating point against h_FE variation and temperature drift. This ensures consistent V_CE(sat) and switching thresholds across batches and operating conditions-critical for reliable logic interfacing where marginal turn-on could cause metastability or increased EMI.
